When it comes to car hard drive video recorders, some people may say, 'That's not car CAM!'! Of course not. Car hard disk recorders, also known as car black boxes, driving recorders and traffic recorders, are just one word. Even the introduction of the two on Baidu Baike has 80% coincidence. No wonder many people think that car hard disk recorders are traffic recorders.

Different definitions

Dash cam: An onboard device used to record images and sounds of vehicles during transportation. It can record video images and sounds of the entire process of vehicle driving, providing evidence for traffic accidents. It can be used as a DV camera at home or as a home monitor.

Car hard drive video recorder: commonly known as the car black box, is a device installed on a car that takes photos from various angles. A digital electronic recording device used to record and store status information such as vehicle speed, time, and mileage, and can output data through an interface.

Different principles

Dash cam: Captures objects in front of the car from the driver's perspective, records and updates the road conditions in front of or around the car through digital video, and even records car records, acceleration, steering, braking, and other information data. Internal sensors can set the sensitivity of the impact force, and when the external impact force exceeds the set value, it will record the on-site data causing the impact, providing evidence for traffic accidents.

Car mounted hard disk recorder: It can shoot and record from multiple angles, with built-in 3G/4G and GPS. It needs to be used in conjunction with external devices such as surveillance cameras, alarm buttons, LCD screens, intercom microphones, speakers, etc. to meet the needs of vehicle supervision teams to build a multipolar monitoring platform and check vehicle dynamics at any time.

Different usage themes

Driving recorder: private car, off-road vehicle.

Vehicle mounted hard disk recorder: Bus, school bus, dirt truck, police car, sanitation car, tourist charter car, heavy truck and other vehicle models, generally used for fleet management.

Outstanding features

Driving recorder: powerful shooting and recording functions, requiring certain storage functions, high image requirements, wide angle night vision, and other functions.

Car mounted hard disk recorder: The device itself does not have video recording function. The external camera can achieve multi-channel video recording, supporting HDD and SD card storage. The external device can achieve cluster intercom, emergency alarm, platform monitoring and other functions.

Taking the Citops M52H device as an example, it uses a high-speed processor HI3521D and embedded Linux, 3G/4G network, GPS/BD, and WIFI. Supports 1080p, 720p, D1 video recording, vehicle driving records, and remote video uploading. With the help of central software, central remote monitoring can be carried out based on alarm linkage, and vehicle intelligent scheduling management and playback analysis can be carried out based on a central database. This device has strong seismic resistance, rich functions, high reliability, simple appearance, and is easy to deploy.
